Description

[Detailed Description of the Invention] The present invention relates to a water leak prevention mechanism for an automobile door.

Conventionally, the inner panel hole provided inside the car door has a working hole for assembling door-related parts, but when it rains or when washing the car, it is difficult to access the door glass opening from the outside of the car body. The water that passes through and enters the interior of the vehicle travels through the inner panel and further leaks into the passenger compartment through the working hole.
To prevent this, a water sheet made of polyethylene or vinyl film is pasted on the work hole and its surrounding area using adhesive, but sometimes the water sheet is not fully adhered. If water leaks, the water leaks into the room through the gap between the periphery of the lower part of the door cover, which is attached to the opening on the indoor side of the door to cover the inner panel, and the periphery of the door opening. This poses a problem in that it is not possible to prevent water leakage due to incomplete pasting work, although the work of pasting the water seal is complicated and time-consuming.

In this invention, the door pad is made of synthetic resin and is integrally molded in a shape extending from the indoor side edge of the door to the outdoor side edge, and by attaching this door pad to the indoor side of the door, water can be removed. The purpose is to eliminate the use of stickers and to prevent water from leaking into the room due to incomplete sticker application.

An example of the implementation of the present invention will be described with reference to the drawings. The material of the door pad 1 attached to the lower half of the indoor side of the door 4 is made of synthetic resin, and the size is such that when the door 4 is closed, the door pad 1 is attached to the door attachment opening of the vehicle body 2. Periphery 2
The door seal joint surface 4a (shaded area) facing the door seal 3 installed in the section A further expands to the outer peripheral edge 4b of the door 4, and the left and right side edges 1a, 1a and lower edge 1b are shaped like the outer peripheral edge 4b of the door 4. The left and right ends of the upper edge 1c of the door pad 1 are molded into a suitable shape, and the left and right ends of the upper edge 1c of the door pad 1 are formed into inclined edges that are inclined diagonally downward toward the outside as shown in FIG. A water guide portion 1d is provided by forming an inclined groove diagonally downward from the upper edge 1c side to the side edge 1a on the back surface in contact with the peripheral edge 4b. Leg portions 6a of a fastener 6 made of soft synthetic resin are inserted into small holes that abut the inside and are bored in the left and right side edges 1a, 1a, the lower edge 1b, and the outer peripheral edge 4b of the door 4.
6a, and the side edges 1a, 1a and lower edge 1b are fixed to the door 4 with fasteners 6.

In the figure, reference numeral 1e indicates a concave portion for running water formed by recessing the back surface of the lower edge 1b of the door pad 1.

Since the present invention is configured as described above, even if water that has entered the door 4 from the door opening 7a of the door glass 7 passes through the working hole 5a of the inner panel 5 and reaches the back surface of the door pad 1, the water will not flow. It travels along the back surface of the door pad 1, reaches the outer peripheral edge 4b of the door 4, and flows to the outside of the door 4. In addition, in the upper half of the door 4, that is, the part above the part where the door pad 1 is attached, there is a contact surface between the outer periphery 4b of the door 4 and the door seal 3 attached to the periphery 2a of the door mounting opening of the vehicle body 2. A portion of the water flowing down flows through water guide portions 1d formed at the left and right ends of the upper edge 1c of the door pad 1.
At the same time, the water flows diagonally downward and outward along the edge, or it flows diagonally downward and outward through the inclined groove which is the water guide part 1d, and the other part of the water flows diagonally downward and outward along the edge. Since water flows down the outer peripheral edge 4b of 4 and falls on the road surface, water does not leak into the interior of the room. There is no need to attach the water seal, there is no risk of water leakage due to incomplete adhesion of the water seal, and the water seal is fully effective in preventing water intrusion and leakage.
In addition, the door pad is easily formed and fixed to the door using fasteners, so it is simple and quick, and compared to conventional pasting work, it is much more efficient and can reduce production costs in terms of materials and labor.
